I have been all over trying to resolve this. Evidently it's a known issue with XP that can be resolved according to some posts I've seen. (forums.modemhelp.ne*/viewtopic.php?t=3888)
By the FCC code I've determined the modem is an Askey. - based on the (LAME) Rockwell/Conexant chipset that we all know and love lol.
The updated driver on their site does not restore the voice functionality.
Does anyone know if there is another driver that I could use or an INF file?
I've tried using the Conexant driver that comes with Win, it's the only one listed that has voice functionality. Also I tried the Rockwell in the post mentioned above...
